When on the ground vs in the air, why is the following true?

Ground - throttle controls RPM, prop control directly affects MP (manifold pressure)

Air - throttle is used to change MP, prop control is used to change RPM

During Runup - Pull back prop control, MP pressure increases (why not decrease?)
